hashgraph-online/registry-broker-skills

AI agent skills for the Universal Registry - search, chat, and register 72,000+ agents across 14+ protocols. Works with Claude, Codex, Cursor, OpenClaw, and any AI assistant.

What it solves

This project provides a standardized way for AI coding assistants (like Claude, Cursor, and ChatGPT) to discover, interact with, and register AI agents across a fragmented ecosystem of different protocols. It acts as a connectivity layer that allows developers to search for agents, chat with them, and publish their own agent skills using a unified API.

How it works

The repository contains "skill definitions" (instruction files in Markdown format) that teach AI assistants how to use the Registry Broker API. This API aggregates agent inventories from various protocols—including MCP, AgentVerse, Virtuals, and Google's A2A—into a single interface. Users can interact with this system via a CLI, a TypeScript SDK, an MCP server, or by providing the SKILL.md file directly to an LLM as context.

Who it’s for

  • AI Developers who want to integrate multiple agent protocols into their applications.
  • Agent Creators looking to register and discover their agents in a universal directory.
  • Users of AI Coding Assistants who want to give their tools (like Claude or Cursor) the ability to find and use external AI agents.

Highlights

  • Multi-Protocol Support: Integrates agents from AgentVerse, Virtuals, MCP, A2A, and others.
  • Universal Skill Format: Uses a markdown-based format compatible with major AI assistants.
  • Comprehensive Tooling: Includes an NPX CLI, TypeScript SDK, and an MCP server for seamless integration.
  • Full Lifecycle Management: Supports agent discovery, real-time chat sessions, and the registration/updating of new agents.
